Context: Given I have an entity with a column called `sign`: @Entity @Table(name = "test" ) @Getter @Setter @AllArgsConstructor @NoArgsConstructor public class TestEntity{ @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "task_id" , nullable = false , updatable = false ) private UUID taskId; @Column(name = "title" , nullable = false ) private boolean sign; } With a pojo defined that I want to project into: public class TestProjection { private boolean title; public TestProjection( boolean title){ this.title = title; } } Now, defining and running the following jpql query public interface TestRepository extends JpaRepository<TestEntity, UUID> { @Query( """ select new some.entity.TestProjection( t.sign ) from TestEntity t """ ) List<TestProjection> getAll(); } leads to an exception org.springframework.dao.InvalidDataAccessApiUsageException: org.springframework.data.jpa.repository.query.BadJpqlGrammarException: Line 2:10 no viable alternative at input 't.sign' ; Bad

'socket' Process finished with exit code 255 I would expect it to resolve `t.sign` to be the `sign` property of the `TestEntity` what I think is what really happens is that `sign` is resolved to be the `sign()` function (i.e. `sign(-10) = -1`). A similar exception occurs, when the column gets renamed to other popular function names such as `log` or `exp`. Renaming the column to `signing` leads to the query working as expected.
